Therefore, if one wants to forcibly cultivate the "Taixuan Classics," it is necessary to first convert the positions of the eight trigrams and geomancy of heaven and earth to the Taixuan system according to the "Great Expanse Mysterious Picture." Then, based on the "Taixuan Classics," deduction must be made, and the results translated back using the "Great Expanse Mysterious Picture." Only then can one know how to correctly cultivate Taixuan at that time and place.
If there is any slight error during this process, then naturally the entire effort is wasted. Moreover, one cannot afford to calculate too slowly. If the qi of heaven and earth change while one is too slow, the whole Taixuan cultivation system will also undergo dynamic changes, rendering the previously calculated methods useless and requiring one to deduce all over again!
